(54)	Method and apparatus for efficiently fixing transformed part of content

(57) Provided are a method and apparatus for effectively fixing scrambled content. The method includes checking fixing information for a program map table (PMT) packet of packets constituting the content, the fixing information being used to fix a transformed part of the content; extracting location information of a next PMT packet containing fixing data for fixing the transformed part of the content from the fixing information of the PMT packet; and fixing the transformed part of the content by using the fixing data in the next PMT packet indicated by the extracted location information. Accordingly, it is possible to easily detect a location of the content, which stores the fixing information, thereby expediting fixing of the transformed content.
